EMBODIMENT First Embodiment

Firstly, air conditioning system 19 in accordance with a first embodiment of the present disclosure is explained with reference to FIG. 1 and FIG. 2. FIG. 1 is a connection schematic view of air conditioning system 19 in accordance with the first embodiment of the present disclosure and FIG. 2 shows an example of room layout of general residence 1 in accordance with the first embodiment of the present disclosure.

Air conditioning system 19 is configured to include outdoor air introducing fan 4, multiple exhaust fans 5 (5 a, 5 b, 5 c, 5 d, 5 e, 5 f, 5 g, 5 h and 5 i), multiple transfer fans 3 (3 a, 3 b, 3 c, 3 d, 3 e, 3 f, 3 g, 3 h and 3 i), multiple circulation fans 6 (6 a, 6 b, 6 c, 6 d, 6 e, 6 f, 6 g, 6 h and 6 i), room temperature sensors 9 (9 a, 9 b, 9 c, 9 d, 9 e, 9 f, 9 g, 9 h and 9 i), room humidity sensors 10 (10 a, 10 b, 10 c, 10 d, 10 e, 10 f, 10 g, 10 h and 10 i), room motion sensors 11 (11 a, 11 b, 11 c, 11 d, 11 e, 11 f, 11 g, 11 h and 11 i), air-conditioned room temperature sensor 12, air-conditioned room humidity sensor 13, air conditioner 7, humidifier 15, dehumidifier 16, air cleaner 40, input/output terminal 18 and system controller 8 a (equal to an air conditioning system controller). Air conditioning system 19 further includes solar power generation panel 51, power conditioner 52, power distribution board 53 and electric power storing section 60.

Air conditioning system 19 is installed in general residence 1, which is an example of house. General residence 1 includes multiple (nine in the present exemplary embodiment) rooms 2 (2 a, 2 b, 2 c, 2 d, 2 e, 2 f, 2 g, 2 h and 2 i) and at least one air-conditioned room 17, which is independent from rooms 2 a to 2 i. General residence 1 (residence) here means one provided as where residents live their private lives and it generally includes a living room, a dining room (kitchen and eating space), bedrooms, storages, children's rooms, and so forth. Rooms served by air conditioning system 19 may be a toilet, a bathroom, a restroom, a dressing room, a hallway, an entrance, and so forth.

In air-conditioned room 17, air transferred from each of rooms 2 a to 2 i by each of circulation fans 6 a to 6 i is mixed with each other. The air is also mixed with outdoor air taken therein by outdoor air introducing fan 4. Temperature, humidity and cleanliness of the air of air-conditioned room 17 are suitably controlled by air conditioner 7, humidifier 15, dehumidifier 16 and air cleaner 40, which are disposed in air-conditioned room 17, so that an air conditioning environment in air-conditioned room 17 is optimized to generate air to be transferred to each of rooms 2 a to 2 i. The air that is air-conditioned in air-conditioned room 17 is transferred to each of rooms 2 a to 2 i by each of transfer fans 3 a to 3 i.

The air of each of rooms 2 a to 2 i is transferred to air-conditioned room 17 by each of circulation fans 6 a to 6 i and is additionally exhausted as outdoor air by each of exhaust fans 5 a to 5 i from each of rooms 2 a to 2 i outside general residence 1. Air conditioning system 19 controls an exhaust volume of each of exhaust fans 5 a to 5 i to exhaust the outdoor air from each of the rooms, and simultaneously controls an air supply volume of outdoor air introducing fan 4 in association with the exhaust volume of each of the exhaust fans to introduce the outdoor air into each of the rooms, to thereby perform mechanical heat recovery ventilation.

Outdoor air introducing fan 4 takes the outdoor air into the rooms of general residence 1 and is equal to an air supply fan or an air supply function of a heat-exchange ventilation fan. As described above, the outdoor air taken by outdoor air introducing fan 4 is introduced into air-conditioned room 17. Outdoor air introducing fan 4 is configured to be able to set multiple supply air volumes and the air volume is set according to the exhaust volume of each of exhaust fans 5 a to 5 i as described later.

Each of exhaust fans 5 a to 5 i exhausts part of the air of each of rooms 2 a to 2 i outside through an exhaust duct and is equal to a function of a ceiling-embedded ventilation fan, a wall-mounted ventilation fan, a range hood or a heat-exchange ventilation fan. In FIG. 1, the exhaust duct connected to each of exhaust fans 5 a to 5 i is directly connected outside general residence 1, however, to use the exhaust function of the heat-exchange ventilation fan, the duct is first connected to the heat-exchange ventilation fan, then connected outside general residence 1. That is, air through the exhaust duct is first heat exchanged with air through an air supply duct of the heat-exchange ventilation fan, then exhausted outside general residence 1. Exhaust fan 5 a is disposed in room 2 a, and equally exhaust fan 5 b is disposed in room 2 b, exhaust fan 5 c is disposed in room 2 c, exhaust fan 5 d is disposed in room 2 d, exhaust fan 5 e is disposed in room 2 e, exhaust fan 5 f is disposed in room 2 f, exhaust fan 5 g is disposed in room 2 g, exhaust fan 5 h is disposed in room 2 h and exhaust fan 5 i is disposed in room 2 i.

The exhaust volume of each of exhaust fans 5 a to 5 i is configured to be able to set multiple exhaust volumes. In normal operation, the exhaust volume of each of exhaust fans 5 a to 5 i is controlled so as to achieve a previously-set exhaust volume. Additionally the exhaust volume of each of exhaust fans 5 a to 5 i is also controlled according to an air volume set by a user or obtained by various sensors.

Transfer fans 3 a to 3 i are disposed, for example, on a wall of air-conditioned room 17 in response to each of rooms 2 a to 2 i. The air of air-conditioned room 17 is transferred to room 2 a by transfer fan 3 a through a transfer duct, and it is equally transferred to room 2 b by transfer fan 3 b, room 2 c by transfer fan 3 c, room 2 d by transfer fan 3 d, room 2 e by transfer fan 3 e, room 2 f by transfer fan 3 f, room 2 g by transfer fan 3 g, room 2 h by transfer fan 3 h and room 2 i by transfer fan 3 i.

Each of the transfer ducts connected to each of the rooms is installed independent from each other.

Circulation fan 6 a is disposed in room 2 a, equally circulation fan 6 b is disposed in room 2 b, circulation fan 6 c is disposed in room 2 c, circulation fan 6 d is disposed in room 2 d, circulation fan 6 e is disposed in room 2 e, circulation fan 6 f is disposed in room 2 f, circulation fan 6 g is disposed in room 2 g, circulation fan 6 h is disposed in room 2 h and circulation fan 6 i is disposed in room 2 i. Part of the air of each of rooms 2 a to 2 i is transferred to air-conditioned room 17 by circulation fans 6 a to 6 i through each of circulation ducts. Each of the circulation ducts connected between air-conditioned room 17 and each of the rooms may be independently installed, however, these separate circulation ducts may be unified into one circulation duct before air-conditioned room 17 and then connected to it.

Air conditioner 7 is equal to an air conditioning controller and controls the air of air-conditioned room 17. Air conditioner 7 cools or heats the air of air-conditioned room 17 so that a temperature of air-conditioned room 17 can reach an air-conditioned room target temperature previously set.

Humidifier 15 humidifies the air of air-conditioned room 17, when a humidity of air-conditioned room 17 is lower than an air-conditioned room target humidity previously set, so as to achieve the air-conditioned room target humidity. Humidifier 15 may be built in air conditioner 7, however, it's desirable to install humidifier 15 independent from air conditioner 7 for obtaining a humidifying capacity enough to humidify each of rooms 2 a to 2 i.

Dehumidifier 16 dehumidifies the air of air-conditioned room 17, when the humidity of air-conditioned room 17 is higher than the air-conditioned room target humidity previously set, so as to achieve the air-conditioned room target humidity. Dehumidifier 16 may be built in air conditioner 7, however, it's desirable to install dehumidifier 16 independent from air conditioner 7 for obtaining a dehumidifying capacity enough to dehumidify each of rooms 2 a to 2 i.

Air cleaner 40 cleans the air of air-conditioned room 17, when a cleanliness of air-conditioned room 17 is higher than an air-conditioned room target cleanliness previously set, so as to achieve the air-conditioned room target cleanliness. Air cleaner 40 may be built in air conditioner 7, however, it's desirable to install air cleaner 40 independent from air conditioner 7 for obtaining a cleaning capacity enough to clean each of rooms 2 a to 2 i.

Room temperature sensor 9 a is disposed in room 2 a, equally room temperature sensor 9 b is disposed in room 2 b, temperature sensor 9 c is disposed in room 2 c, temperature sensor 9 d is disposed in room 2 d, temperature sensor 9 e is disposed in room 2 e, temperature sensor 9 f is disposed in room 2 f, temperature sensor 9 g is disposed in room 2 g, temperature sensor 9 h is disposed in room 2 h and temperature sensor 9 i is disposed in room 2 i. Each of room temperature sensors 9 a to 9 i obtains each of indoor temperature of rooms 2 a to 2 i to transmit it to system controller 8 a.

Room humidity sensor 10 a is disposed in room 2 a, equally room humidity sensor 10 b is disposed in room 2 b, room humidity sensor 10 c is disposed in room 2 c, room humidity sensor 10 d is disposed in room 2 d, room humidity sensor 10 e is disposed in room 2 e, room humidity sensor 10 f is disposed in room 2 f, room humidity sensor 10 g is disposed in room 2 g, room humidity sensor 10 h is disposed in room 2 h and room humidity sensor 10 i is disposed in room 2 i. Each of room humidity sensors 10 a to 10 i obtains each of indoor humidity of rooms 2 a to 2 i to transmit it to system controller 8 a.

Room motion sensor 11 a is disposed in room 2 a, equally room motion sensor 11 b is disposed in room 2 b, room motion sensor 11 c is disposed in room 2 c, room motion sensor lid is disposed in room 2 d, room motion sensor lie is disposed in room 2 e, room motion sensor 11 f is disposed in room 2 f, room motion sensor 11 g is disposed in room 2 g, room motion sensor 11 h is disposed in room 2 h and room motion sensor 11 i is disposed in room 2 i. Each of room motion sensors 11 a to 11 i obtains an occupancy/unoccupancy information of each of rooms 2 a to 2 i to transmit it to system controller 8 a. Room motion sensor 11 may be in any form if it is a device to detect whether each of rooms 2 a to 2 i is occupied or unoccupied. That is, room motion sensor 11, for example, is equal to an infrared radiation sensor, an image sensor, a carbon dioxide sensor and others, which directly detect whether room 2 is occupied or unoccupied. However, their accuracy and property are different each other, therefore, they may be used according to purpose. For example, a communicator used in proximity wireless communication is equal to room motion sensor 11 in this application when an occupancy/unoccupancy in room 2 is determined through a communication between a mobile communication terminal and the communicator installed in room 2.

Air-conditioned room temperature sensor 12 obtains the temperature of air-conditioned room 17 to transmit it to system controller 8 a. Air-conditioned room temperature sensor 12 may be built in air conditioner 7, however, in that case, it can obtain only information around air conditioner 7 (for example, information around an air supply inlet). As described above, the outdoor air and the air transferred from rooms 2 a to 2 i are mixed in air-conditioned room 17, therefore, it's desirable to install it independent from air conditioner 7 so as to obtain whole information on air-conditioned room 17.

Air-conditioned room humidity sensor 13 obtains the humidity of air-conditioned room 17 to transmit it to system controller 8 a. For the same reason as that for air-conditioned room temperature sensor 12, it's desirable to install it independent from air conditioner 7 so as to obtain whole information on air-conditioned room 17.

Solar power generation panel 51 is installed on a roof of general residence 1, which is an example of natural energy power generator, to generate power by receiving sunlight.

Power conditioner 52 is connected to solar power generation panel 51 and converts DC (direct current) electricity generated by solar power generation panel 51 to AC (alternate current) electricity normally available in general residence 1. Power conditioner 52 is also connected to electric power storing section 60 and stores DC (direct current) electricity generated by solar power generation panel 51 in electric power storing section 60. Power conditioner 52 supplies an electric power drawn from electric power storing section 60 to power distribution board 53 accordingly.

Power distribution board 53 is connected to power conditioner 52 to provide (distribute) the AC (alternate current) electricity output by power conditioner 52 to power-consuming equipment including appliances, bulbs or lightings and others (hereinafter referred to as power-consuming equipment). The power-consuming equipment includes system controller 8 a and the air conditioning controller. That is, the air conditioning controller means equipment to air condition general residence 1, and is equal to transfer fan 3, circulation fan 6, air conditioner 7, humidifier 15, dehumidifier 16, air cleaner 40, room temperature sensor 12, air-conditioned room temperature sensor 12, room motion sensor 11 and others in this application. Other than these, it includes all power-consuming equipment connected to power distribution board 53 such as a refrigerator, a washing machine or a television other than the air conditioning controller installed in general residence 1.

Electric power storing section 60 is equal to a so-called storage battery. Electric power storing section 60 obtains and stores a surplus electric power through power conditioner 52, the surplus electric power is the electric power generated by solar power generation panel 51 and does not include the electric power amount consumed within the house. The surplus electric power stored in electric power storing section 60 is consumed by being supplied to power distribution board 53 through power conditioner 52 accordingly.

System controller 8 a controls overall air conditioning system 19. System controller 8 a is wirelessly connected in such a way as to be able to communicate with outdoor introducing fan 4, exhaust fans 5 a to 5 i, transfer fans 3 a to 3 i, circulation fans 6 a to 6 i, room temperature sensors 9 a to 9 i, room humidity sensors 10 a to 10 i, room motion sensors 11 a to 11 i, air-conditioned room temperature sensor 12, air-conditioned room humidity sensor 13, air conditioner 7, humidifier 15 and dehumidifier 16, air cleaner 40 and power distribution board 53.

System controller 8 a controls outdoor air introducing fan 4 and exhaust fans 5 a to 5 i in association with each other. For example, system controller 8 a may set the air supply volume of outdoor air introducing fan 4 according to the exhaust volume of each of exhaust fans 5 a to 5 i. This makes it possible to provide mechanical heat recovery ventilation for general residence 1.

In addition, system controller 8 a controls air conditioner 7, humidifier 15 and dehumidifier 16 as the air-controlling controller according to the temperature and humidity of air-conditioned room 17 obtained by air-conditioned room temperature sensor 12 and air-conditioned room humidity sensor 13 such that at least one of the temperature and the humidity of air-conditioned room 17 can be at least one of the target temperature and the target humidity previously set to air-conditioned room 17. System controller 8 a also controls air cleaner 40 as the air conditioning controller such that air-conditioned room 17 can be a target air conditioning environment cleanliness previously set to air-conditioned room 17.

Moreover, system controller 8 a determines whether each of rooms 2 a to 2 i is occupied or unoccupied according to occupancy/unoccupancy information on each of rooms 2 a to 2 i obtained by each of room motion sensors 11 a to 11 i.

Then, system controller 8 a sets the air volume of each of transfer fans 3 a to 3 i and the air volume of each of circulation fans 6 a to 6 i according to the indoor temperature and the indoor humidity of each of rooms 2 a to 2 i obtained by each of room temperature sensors 9 a to 9 i and each of room humidity sensor 10 a to 10 i, a target air conditioning temperature, a target air conditioning humidity and the like set to the occupied room.

Moreover, system controller 8 a sets the air volume of each of transfer fans 3 a to 3 i and the air volume of each of circulation fans 6 a to 6 i according to the indoor temperature and the indoor humidity of each of rooms 2 a to 2 i obtained by each of room temperature sensors 9 a to 9 i and each of room humidity sensors 10 a to 10 i and a quasi-target air conditioning temperature and a quasi-target air conditioning humidity and the like set to the unoccupied room.

Thus, the air conditioned in air-conditioned room 17 is transferred to each of rooms 2 a to 2 i at the air volume set to each of transfer fans 3 a to 3 i and the air of each of rooms 2 a to 2 i is transferred to air-conditioned room 17 at the air volume set to each of circulation fans 6 a to 6 i. Therefore, at least one of the indoor temperature, the indoor humidity and the cleanliness of each of rooms 2 a to 2 i is controlled so as to be at least one of the target air conditioning temperature, the target air conditioning humidity and the target air conditioning cleanliness.

And, system controller 8 a obtains the electric power amount from power distribution board 53, the electric power amount is a power generation amount generated by solar power generation panel 51. Of course, system controller 8 a may obtain the power generation amount directly from power conditioner 52. The power generation amount here means an electric power currently generated by solar power generation panel 51, however, it may further include the surplus electric power that is previously generated by solar power generation panel 51 and already stored in electric power storing section 60. In this case, a sum of the electric power currently generated by solar power generation panel 51 and the electric power available by electric power storing section 60 is equal to the generation power amount. When solar power generation panel 51 does not generate power, for example, at night, only available electric power already stored in electric power storing section 60 is equal to the generation power amount.

In addition, system controller 8 a obtains the electric power currently consumed by all power-consuming equipment connected to power distribution board 53 from there. If possible, power distribution board 53 may obtain how much electric power each power-consuming equipment (for example, air conditioner 7) consumes. Specifically, power distribution board 53 is segmented into several power-supply branch lines (segment), then an air conditioning-related power-consuming equipment, that is, the air conditioning controller, is connected to one segment, thus system controller 8 a can obtain an electric power amount consumed only by the air conditioning controller.

A process of above-described system controller 8 a is detailed hereinafter.

Here, no complicated wiring is required by connecting system controller 8 a with outdoor air introducing fan 4, exhaust fans 5 a to 5 i, transfer fans 3 a to 3 i, circulation fans 6 a to 6 i, room temperature sensors 9 a to 9 i, room humidity sensors 10 a to 10 i, room motion sensors 11 a to 11 i, air-conditioned room temperature sensor 12, air-conditioned room humidity sensor 13, air conditioner 7, humidifier 15 and dehumidifier 16, air cleaner 40 and power distribution board 53 using wireless communication. On the other hand, it is also possible that all of these components, or system controller 8 a and a part of them, may be configured to communicate with each other by wired communication.

Input/output terminal 18 is connected in such a way to be able to communicate with system controller 8 a by wireless communication. Input/output terminal 18 receives information required to construct air conditioning system 19 to store it on system controller 8 a or displays a status of air conditioning system 19 obtained from system controller 8 a. An example of input/output terminal 18 is a portable information terminal such as a mobile phone, a smart phone, or a tablet.

Input/output terminal 18 may not always be connected to system controller 8 a by the wireless communication, therefore, it may be connected to system controller 8 a to be able to communicate with each other by the wired communication. In this case, for example, input/output terminal 18 may be a wall-mounted remote controller.

Next, functions of system controller 8 a are explained with reference to FIG. 3. FIG. 3 is a schematic function block diagram of system controller 8 a.

System controller 8 a includes air-conditioned room temperature controlling section 23, air volume determining section 24 a, fan air volume controlling section 20, total air volume calculating section 25, air volume comparing section 26 and storing section 30. System controller 8 a further includes in-house power generation amount obtaining section 54, electric power amount obtaining section 55, comparing section 56 and control switching section 59.

Air-conditioned room temperature controlling section 23 controls air conditioner 7 as the air conditioning controller so that a temperature of air-conditioned room 17 (air-conditioned room temperature) can be equivalent to a target air conditioning environment (temperature) or less obtained by target air conditioning environment obtaining section 33 a during a cooling period when the indoor temperature (room inside temperature) of room 2 is high and air conditioner 7 provides cooling operation. Air-conditioned room temperature controlling section 23 controls air conditioner 7 so that the temperature of air-conditioned room 17 (air-conditioned room temperature) can be equivalent to the target air conditioning environment (temperature) or over obtained by target air conditioning environment obtaining section 33 a during a heating period when the indoor temperature of room 2 is low and air conditioner 7 provides heating operation.

Air volume determining section 24 a includes sensor information obtaining section 35, occupied-room/unoccupied-room determining section 32, target air conditioning environment obtaining section 33 a, quasi-target air conditioning environment storing section 34 a, occupied-room air conditioning environment controlling section 21, unoccupied-room air conditioning environment controlling section 22, first temperature comparing section 27, second temperature comparing section 28 and temperature difference comparing section 29.

Sensor information obtaining section 35 is connected to room temperature sensors 9 a to 9 i, room motion sensors 11 a to 11 i, air-conditioned room temperature sensor 12, room humidity sensors 10 a to 10 i and an air-cleanliness sensor to obtain each of information obtained by each sensor. Where each of room motion sensors 11 a to 11 i detects whether each of rooms 2 a to 2 is occupied or unoccupied, room motion sensor 11 is equal to a human-detection section and sensor information obtaining section 35 is equal to a human-detection information obtaining section.

Occupied-room/unoccupied-room determining section 32 determines whether each of rooms 2 a to 2 i is occupied or unoccupied according to the information obtained from each of room motion sensors 11 a to 11 i through sensor information obtaining section 35. Each of room motion sensors 11 a to 11 i itself may determine the occupancy/unoccupancy to transmit a signal indicating a determination to occupied-room/unoccupied-room determining section 32 or occupied-room/unoccupied-room determining section 32 may determine the occupancy/unoccupancy according to the signal transmitted from each of room motion sensors 11 a to 11 i.

When room 2 is determined as being occupied by occupied-room/unoccupied-room determining section 32, target air conditioning environment obtaining section 33 a obtains the target air conditioning environment (temperature) previously set to occupied room 2 through input/output terminal 18.

Occupied-room air conditioning environment controlling section 21 determines the air volume of transfer fan 3 of the occupied room according to the target air conditioning environment (temperature) obtained by target air conditioning environment obtaining section 33 a, the temperature of air-conditioned room 17 controlled by air-conditioned room temperature controlling section 23 or obtained through air-conditioned room temperature sensor 12 and the indoor temperature of the occupied room obtained by room temperature sensor 9.

Quasi-target air conditioning environment storing section 34 a associates an adjacent spatial distance between the occupied room and the unoccupied room with a quasi-target air conditioning environment (temperature) corresponding to the adjacent spatial distance.

Here, the adjacent spatial distance means a distance between the occupied room and the unoccupied room. However, given that a room is considered as one space, the distance does not mean a linear one, but a value indicating how much spaces exist between the occupied room and the unoccupied room. For example, the adjacent spatial distance is one (1) for an adjacent room where it is adjacent to the occupied room across an accessible door. The adjacent spatial distance is not one (1) for the adjacent room where it is not directly accessible to the occupied room even if it is adjacent to the occupied room. The adjacent spatial distance is two (2) for a room where it is connected with the occupied room through an accessible hallway. A specific example is subsequently given with reference to FIG. 2. When room 2 a is occupied and rooms 2 b to 2 i are unoccupied, the adjacent spatial distance is one (1) for room 2 c, two (2) for room 2 b, 2 d, 2 e and 2 h and three (3) for room 2 f, 2 g and 2 i. And when room 2 a and room 2 i are occupied and rooms other than these are unoccupied, the adjacent spatial distance is one (1) for room 2 c and room 2 h and two (2) for room 2 b, 2 d, 2 e, 2 g and 2 f.

The quasi-target air conditioning environment means an air conditioning environment where an energy burden is lower than that of the target air conditioning environment. Here, the air conditioning environment with the lower energy burden is explained taking the temperature as an example. During summer, that is, the cooling period, given that the target air conditioning environment (temperature) of the occupied room is set to 24 degrees C. In this case, the quasi-target air conditioning environment (temperature) is higher than 24 degrees C., that is, an environment where air conditioner 7 consumes less electric power, for example, 26 degrees C. During winter, that is, the heating period, given that the target air conditioning environment (temperature) of the occupied room is set to 22 degrees C. In this case, the quasi-target air conditioning environment (temperature) is lower than 22 degrees C., that is, the air conditioning environment where air conditioner 7 consumes less electric power, for example, 20 degrees C.

The quasi-target air conditioning environment is explained taking the temperature as the example in the above. For the humidity, in an environment requiring dehumidification during a rainy season, the quasi-target air conditioning environment (humidity) means an environment where the humidity is set to be higher than that in the target air conditioning environment (humidity), and the quasi-target air conditioning environment (humidity) means an environment where the humidity is set to be lower than that in the target air conditioning environment (humidity) during a dry season. For the cleanliness, the quasi-target air conditioning environment (cleanliness) is an environment where the cleanliness is set to be higher than that in the target air conditioning environment (cleanliness). The cleanliness is detected by the cleanliness sensor such as a dust sensor or the carbon dioxide sensor installed in air-conditioned room 17, for example.

A setting example of the target air conditioning environment (temperature) and the quasi-target air conditioning environment (temperature) of the room is indicated below according to information stored in quasi-target air conditioning environment storing section 34 a.

During summer, that is, the cooling period, quasi-target air conditioning environment storing section 34 a stores the quasi-target air conditioning environment (temperature) 2 degrees C. higher than the target air conditioning environment (temperature) when the adjacent spatial distance is one (1) between the occupied room and the unoccupied room. When the adjacent spatial distance is two (2) between the same, quasi-target air conditioning environment storing section 34 a stores the quasi-target air conditioning environment (temperature) 4 degrees C. higher than the target air conditioning environment (temperature). When the adjacent spatial distance is three (3) between the same, quasi-target air conditioning environment storing section 34 a stores the quasi-target air conditioning environment (temperature) 6 degrees C. higher than the target air conditioning environment (temperature). Considering where all of rooms 2 a to 2 i are unoccupied or the adjacent spatial distance between the occupied room and the unoccupied room is significantly large, for example, 4 or over, quasi-target air conditioning environment storing section 34 a stores the quasi-target air conditioning environment (temperature) up to 8 degrees C. higher than the target air conditioning environment (temperature) during the cooling period.

Similarly, during winter, that is, the heating period, quasi-target air conditioning environment storing section 34 a stores the quasi-target air conditioning environment (temperature) 2 degrees C. lower than the target air conditioning environment (temperature) when the adjacent spatial distance is one (1) between the occupied room and the unoccupied room. When the adjacent spatial distance is two (2) between the same, quasi-target air conditioning environment storing section 34 a stores the quasi-target air conditioning environment (temperature) 4 degrees C. lower than the target air conditioning environment (temperature). When the adjacent spatial distance is three (3) between the same, quasi-target air conditioning environment storing section 34 a stores the quasi-target air conditioning environment (temperature) 6 degrees C. lower than the target air conditioning environment (temperature). Considering where all of rooms 2 a to 2 i are unoccupied or the adjacent spatial distance between the occupied room and the unoccupied room is significantly large, for example, 4 or over, quasi-target air conditioning environment storing section 34 a stores the quasi-target air conditioning environment (temperature) up to 8 degrees C. lower than the target air conditioning environment (temperature) during the heating period.

For example, in FIG. 2, given that room 2 a is occupied and rooms 2 b to 2 i are unoccupied during summer, that is, the cooling period, where the target air conditioning environment (temperature) is 20 degrees C. for room 2 a, the quasi-target air conditioning environment (temperature) is 22 degrees C. for rooms 2 b and 2 c because the adjacent spatial distance is one (1), the quasi-target air conditioning environment (temperature) is 24 degrees C. for rooms 2 d, 2 e and 2 h because the adjacent spatial distance is two (2) and the quasi-target air conditioning environment (temperature) is 26 degrees C. for rooms 2 f, 2 g and 2 i because the adjacent spatial distance is three (3). FIG. 4 indicates a temperature distribution diagram where room 2 a is occupied and rooms 2 b to 2 i are unoccupied during summer, that is, the cooling period, and the same concentration means the same temperature.

Unoccupied-room air conditioning environment controlling section 22 determines the air volume of transfer fan 3 of the unoccupied room according to the quasi-target air conditioning environment (temperature) determined by information from target air conditioning environment obtaining section 33 a and quasi-target air conditioning environment storing section 34 a, the temperature of air-conditioned room 17 controlled by air-conditioned room temperature controlling section 23 or obtained through air-conditioned room temperature sensor 12 and the indoor temperature of the unoccupied room obtained by room temperature sensor 9. A procedure to determine or modify the air volume is explained hereinafter.

First temperature comparing section 27 calculates a temperature difference between the target air conditioning temperature obtained by target air conditioning environment obtaining section 33 a and the temperature of the air-conditioned room detected by air-conditioned room sensor 12 per occupied room. First temperature comparing section 27 also calculates a temperature difference between the quasi-target air conditioning temperature determined through quasi-target air conditioning environment storing section 34 a and the temperature of the air-conditioned room detected by air-conditioned room sensor 12 per unoccupied room.

Second temperature comparing section 28 calculates a temperature difference between the target air conditioning temperature obtained by target air conditioning environment obtaining section 33 a and the indoor temperature of the occupied room detected by room temperature sensor 9 per occupied room. Second temperature comparing section 28 also calculates a temperature difference between the quasi-target air conditioning temperature determined through quasi-target air conditioning environment storing section 34 a and the indoor temperature of the unoccupied room detected by room temperature sensor 9 per unoccupied room.

Temperature difference comparing section 29 compares a temperature difference A calculated by second temperature comparing section 28 at a specified timing A with a temperature difference B calculated by second temperature comparing section 28 at a timing B when a given time lapses from the specified timing A. The timing A can be reworded as a specified time and the timing B as a time when the given time lapses from the specified time.

Fan air volume controlling section 20 controls the air volume of each of transfer fans 3 a to 3 i to be the air volume determined by air-volume determining section 24 a for each of rooms 2 a to 2 i. Fan air volume controlling section 20 may also control the air volume of each of circulation fans 6 a to 6 i, however, the detailed explanation is omitted here.

Total air volume calculating section 25 calculates a total air volume, which is a sum of the air volume of each of transfer fans 3 a to 3 i. Here, the sum of the air volume is indicated as the sum of the air volume of each of transfer fans 3 a to 3 i per unit time.

Air volume comparing section 26 compares the total air volume calculated by total air volume calculating section 25 with a specified threshold value of the air volume. Here the specified threshold value of the air volume may be, for example, a sum of maximum air volume of each of transfer fans 3 a to 3 i, or 70% to 95% of the sum of the maximum air volume.

Storing section 30 is, so called, a memory which stores the specified threshold value of the air volume previously set. Storing section 30 is also used when a control by system controller 8 a requires information such as numerical values to be stored.

In-house power generation amount obtaining section 54 obtains the power generation amount generated by solar power generation panel 51 through power distribution board 53.

Electric power amount obtaining section 55 obtains the electric power amount consumed in general residence 1 through power distribution board 53. Here, a process may be included to calculate the electric power amount consumed by all power-consuming equipment according to the electric power amount consumed by each of the power-consuming equipment.

Comparing section 56 compares the power generation amount obtained by in-house power generation amount obtaining section 54 with the consumed electric power amount obtained by electric power amount obtaining section 55 to determine whether or not there is a surplus electric power amount and an amount of it. Here, the surplus electric power amount is calculated by subtracting the consumed electric power amount from the power generation amount. That is, when the surplus electric power amount is positive, the power generation amount exceeds the consumed electric power amount.

Control switching section 59 includes normal energy controlling section 57 and energy-saving controlling section 58 to switch between a normal energy control of normal energy controlling section 57 and an energy-saving control of energy-saving controlling section 58 according to a user input through input/output terminal 18.

Normal energy controlling section 57 achieves a user-desired target air conditioning environment by the normal energy control regardless of the surplus electric power amount, in other words, regardless of the consumed electric power amount.

Energy-saving controlling section 58, when there is the surplus electric power amount, achieves the user-desired target air conditioning environment by the energy-saving control as possible within a range of the surplus electric power amount.

Next, an air conditioning process executed by system controller 8 a, mainly in the normal energy control, is explained with reference from FIG. 5 through FIG. 10. FIG. 5 is a flow chart showing the air conditioning process. FIG. 6 an example of relationship between the temperature of the air-conditioned room, a room indoor temperature and the target (quasi-target) air conditioning temperature. FIG. 7 is a flow chart showing an air-conditioned room temperature control process. FIG. 8 is a flow chart showing a fan air volume setting process. FIG. 9 is a flow chart showing a fan air volume adjusting process. FIG. 10 is a flow chart showing an air-conditioned room load reduction process.

To start the air conditioning process, control switching section 59, which is part of system controller 8 a, firstly confirms whether an operating mode is the normal energy control or the energy-saving control, the operating mode is input through input/output terminal 18 by the user and stored in storing section 30 (S1).

Here, when the operating mode is the normal energy control, control switching section 59 executes a process below through normal energy controlling section 57 (Yes for S1). The normal energy control is the operating mode for controlling the air conditioning controller so that the air conditioning environment of general residence 1 can be close to the user-desired target air conditioning environment regardless of the surplus electric power amount.

Normal Energy Control

The air conditioning process executed by system controller 8 a, as indicated in FIG. 5, mainly includes air-conditioned room temperature control process S100, fan air volume setting process S200 and fan air volume adjusting process S300, and these processes are executed in this order.

In the normal energy control, system controller 8 a firstly executes air-conditioned room temperature control process S100 indicated in FIG. 7. In air-conditioned room temperature control process S100, system controller 8 a obtains a heating/cooling period setting set by input/output terminal 18 (S101). Here, in the heating/cooling period setting, for example, the cooling period is set in summer when a temperature is high and air conditioner 7 operates as a cooler, and the heating period is set in winter when a temperature is low and air conditioner 7 operates as a heater. For example, the user sets a duration from June to September as the cooling period, and another duration from December to March as the heating period to a calendar function of input/output terminal 18, thus system controller 8 a can obtain either the cooling period setting or the heating period setting.

Then, system controller 8 a obtains the target air conditioning temperature set to the occupied room by input/output terminal 18 through target air conditioning environment obtaining section 33 a (S102).

After system controller 8 a obtains the target air conditioning temperature, then air-conditioned room temperature controlling section 23 sets the target temperature of air-conditioned room 17 (the target air conditioning temperature of the air-conditioned room) to air conditioner 7 (S103). It is specifically set as described below.

FIG. 6 illustrates each temperature environment in air-conditioned room 17, occupied room 2 d, unoccupied room 2 c and unoccupied room 2 b. The cooling period is taken as an example here. In occupied room 2 d, the indoor temperature is 27 degrees C. and the target air conditioning temperature is 20 degrees C. In unoccupied room 2 c, the indoor temperature is 27 degrees C., and the quasi-target air conditioning temperature is 22 degrees C. because the adjacent spatial distance from occupied room 2 d is one (1). In unoccupied room 2 b, the indoor temperature is 28 degrees C., and the quasi-target air conditioning temperature is 24 degrees C. because the adjacent spatial distance from occupied room 2 d is two (2). Here, the heating/cooling period setting is obtained as the cooling period according to the process of S101, that is, the cooling operation is provided. Therefore air-conditioned room temperature controlling section 23 controls the target air conditioning temperature of the air-conditioned room to be equal to or less than the target air conditioning temperature. As indicated in the example of FIG. 5, the target air conditioning temperature of the air-conditioned room is set to 20 degrees C. or less. The target air conditioning temperature of the air-conditioned room is 20 degrees C. here.

During the heating period, that is, the heating operation is provided, air-conditioned room temperature controlling section 23 controls the target air conditioning temperature of the air-conditioned room to be equal to or higher than the target air conditioning temperature. Although no example is taken as indicated in FIG. 6 here, the target air conditioning temperature is 24 degrees C. during the heating period, for example.

According to the above setting, air-conditioned room 17 is cooled to 20 degrees C., which is the setting temperature, this target air conditioning temperature of the air-conditioned room satisfies the target air conditioning temperature of each of rooms 2 b, 2 c and 2 d (between 20 and 24 degrees C. here).

Next, system controller 8 a executes fan air volume setting process S200 as indicated in FIG. 8. In fan air volume setting process S200, system controller 8 a obtains the temperature of the air-conditioned room through air-conditioned room temperature sensor 12 (S201). Subsequently, system controller 8 a obtains the indoor temperature of each of rooms 2 a to 2 i through each of room temperature sensors 9 a to 9 i (S202). Then, system controller 8 a determines whether each of rooms 2 a to 2 i is occupied or unoccupied through occupied-room/unoccupied-room determining section 32 (S203). Additionally, system controller 8 a, when the room is determined as being occupied, obtains the target air conditioning temperature of the occupied room set by input/output terminal 18 through target air conditioning environment obtaining section 33 a, and when the room is determined as being unoccupied, it also obtains the quasi-target air conditioning temperature of the unoccupied room obtained by quasi-target air conditioning environment storing section 34 a according to the information from target air conditioning environment obtaining section 33 a (S204).

After the above process is completed, first temperature comparing section 27 compares the target (quasi-target) air conditioning temperature with the temperature of the air-conditioned room to calculate the temperature difference (S205).

After first temperature comparing section 27 calculates the temperature difference, air volume determining section 24 a determines the air volume of each of transfer fans 3 a to 3 i according to the calculated temperature difference (S206).

The air volume is specifically determined as described below. That is, because the target air conditioning temperature of occupied room 2 d is 20 degrees C. and the temperature of air-conditioned room 18 after conditioned is 20 degrees C., the air volume of transfer fan 3 c passing through the transfer duct connected between occupied room 2 d and air-conditioned room 17 is made maximum. Here, the air volume can be considered as a transfer fan capacity or an operating notch. For example, given that the air volume of transfer fan 3 can be set in ascending (volume) order between Air Volume 1 and Air Volume 10, the air volume is determined as Air Volume 10 here. That is, air volume determining section 24 a determines to transfer a maximum air volume of the same temperature as air-conditioned room 17 (20 degrees C.) to reduce the indoor temperature of occupied room 2 d from 27 degrees C. and further maintain the target air conditioning temperature of 20 degrees C.

Because the quasi-target air conditioning temperature of unoccupied room 2 c with the adjacent spatial distance of one (1) is 22 degrees C. and the temperature of air-conditioned room 17 after conditioned is 20 degrees C., for example, given that the air volume of transfer fan 3 b is Air Volume 10 (maximum), the quasi-target air conditioning temperature of unoccupied room 2 c may be below 22 degrees C. Therefore, air volume determining section 24 a determines the air volume of transfer fan 3 b to be below the maximum value, that is, Volume 8, for example.

Similarly, because the quasi-target air conditioning temperature of unoccupied room 2 b with the adjacent spatial distance of two (2) is 24 degrees C. and the temperature of air-conditioned room 17 after conditioned is 20 degrees C., for example, given that the air volume of transfer fan 3 a is Air Volume 10 (maximum), the quasi-target air conditioning temperature of unoccupied room 2 b may be below 24 degrees C. Therefore, air volume determining section 24 a determines the air volume of transfer fan 3 a to be below the maximum value, that is, Volume 6, for example.

That is, air volume determining section 24 a, according to the temperature difference between the target (quasi-target) air conditioning temperature and the temperature of the air-conditioned room, determines the air volume of transfer fan 3 of the room where the temperature difference calculated by first temperature comparing section 27 is small (for example, occupied room 2 d: temperature difference of 0 degree C.) more than the air volume of transfer fan 3 of the room where the temperature difference is large (for example, unoccupied room 2 b: temperature difference of 5 degrees C., unoccupied room 2 c: temperature difference of 2 degrees C.).

The above process is executed to all the rooms (No for S207→S202, Yes for S207).

Fan air volume controlling section 20 controls the air volume of each of transfer fans 3 a to 3 i according to the air volume of each of transfer fans 3 a to 3 i determined by air volume determining section 24 a.

Thus, it makes possible to control the occupied room to be the target air conditioning temperature and the unoccupied room to be the quasi-target air conditioning temperature through the temperature of the air-conditioned room controlled by air-conditioned room temperature controlling section 23 and separate control of each of transfer fans 3 a to 3 i.

The above process can provide the user-desired, that is, most comfortable target air conditioning environment in the occupied room and the quasi-target air conditioning environment with the lower energy burden in the unoccupied room. Thus, compared to an energy burden where the target air conditioning environment is set to each of the rooms, it can be lowered. And that, even if an occupant moves from the occupied room to the unoccupied room, the occupant is unaffected by a change in the air conditioning environment. Therefore, an adverse effect brought by a sudden environmental change, for example, a shock from the temperature change, can be controlled.

In addition, the unoccupied room is provided with the air conditioning environment where the energy burden is gradationally lowered according to the adjacent spatial distance from the occupied room. Thus, even if the occupant moves over multiple spaces, the environment gradually changes. Therefore, it's easy for the occupant to accept the environment, and the adverse effect associated with environment change can be reduced.

Based on the above process, when the occupant moves to an unoccupied room, the unoccupied room becomes an occupied room, and additionally the occupied room becomes the unoccupied room. Therefore, the target air conditioning environment of the former occupied room is set to the newly-occupied room, then, the most comfortable environment can be provided. As the quasi-target air conditioning environment with the lower energy burden is set to the former occupied room, it makes possible to maintain the environment with the lower energy burden all over the house.

Regardless of the temperature difference between the room indoor temperature and the target (quasi-target) temperature, it is also possible to quickly achieve the target (quasi-target) temperature by transferring the maximum air volume first to a room where the target (quasi-target) temperature is not achieved. Again, after-described fan air volume adjusting process S300 can also maintain each of the rooms at the target (quasi-target) temperature. However, as a large air volume is transferred to multiple rooms 2 from air-conditioned room 17 at one time, the air in air-conditioned room 17 is not be cooled or heated enough, eventually a cooling and heating effect may be reduced. This is the case when the air conditioning system starts any process or the target air conditioning environment is simultaneously set to each of the rooms after all family occupants come home. To cope with this problem, a volume of the air-conditioned room may be increased, however, this not only increases a space cost but also requires a large capacity of air-conditioner. While on the other hand, air volume determining section 24 a determines the air volume of the transfer fan of the room where the temperature difference is small more than that of the room where the temperature difference is large. In other words, air volume determining section 24 a determines the air volume of the transfer fan of the room where the temperature difference is large less than that of the room where the temperature difference is small. Thus, the indoor temperature of each of the rooms can be gradually reduced to the target (quasi-target) air conditioning temperature to control a reduction in the cooling and heating effect and downsize the air-conditioned room as a result.

By the way, in the above setting, as the target air conditioning temperature of occupied-room 2 d is the same as that of air-conditioned room 17, occupied-room 2 d can be controlled to be at the target air conditioning temperature by controlling transfer fan 3 c to transfer the maximum air volume. However, as the quasi-target air conditioning temperature of unoccupied-room 2 b is 24 degrees C., where the air volume is Air Volume 5 in the above example, it is not clear whether the quasi-target air conditioning temperature can be achieved, the achieved quasi-target air conditioning temperature can be maintained or unoccupied-room 2 b is overcooled. It is the same in unoccupied-room 2 c. To cope with a case like this, system controller 8 a executes fan air volume adjusting process S300 indicated in FIG. 9. In fan air volume adjusting process S300, system controller 8 a determines whether or not the given time lapses after fan air volume setting process S200 is completed (S301). When it does not lapse, system controller 8 a waits until it lapses (No for S301). This intends to operate the air conditioning system in an environment set by fan air volume setting process S200 and secure a time to approximate the indoor temperature of each of the rooms to the target air conditioning temperature.

After the given time lapses, system controller 8 a obtains the indoor temperature of each of the rooms through each of room temperature sensors 9 a to 9 i (S302). In addition, system controller 8 a determines whether each of rooms 2 a to 2 i is occupied or unoccupied through occupied-room/unoccupied-room determining section 32 (S303). Then, system controller 8 a, when the room is determined as being occupied, obtains the target air conditioning temperature of the occupied room set by input/output terminal 18 through target air conditioning environment obtaining section 33 a, and when the room is determined as being unoccupied, it also obtains the quasi-target air conditioning temperature of the unoccupied room obtained by quasi-target air conditioning environment storing section 34 a according to the information from target air conditioning environment obtaining section 33 a (S304).

After the above process is completed, second temperature comparing section 28 compares the target (quasi-target) air conditioning temperature with the indoor temperature of the room to calculate the temperature difference (temperature divergence) (S305).

After second temperature comparing section 28 calculates the temperature difference, temperature difference comparing section 29 compares it with the temperature difference A. The temperature difference A is calculated by second temperature comparing section 28 at a previous timing (equal to the timing A) and stored in fan air volume adjusting process S300 previously executed. As this is the first process, the temperature difference A previously calculated does not exist, therefore no comparison is provided. The calculated temperature difference is stored in storing section 30 as the temperature difference A, and then system controller 8 a returns to S301.

When the temperature difference A calculated at the previous timing (equal to the timing A) exists, temperature difference comparing section 29 compares the temperature difference B calculated by second temperature comparing section 28 at this timing (equal to the timing B) with the temperature difference A at the timing A stored in storing section 30.

Here, when the indoor temperature of the room is close to the target (quasi-target) air conditioning temperature after a lapse of time from the timing A to the timing B, that is, the temperature difference B is smaller than the temperature difference A, it means that the indoor temperature of the room is close to the target (quasi-target) air conditioning temperature by operation of transfer fan 3. Therefore, air volume determining section 24 a determines to reduce the air volume of transfer fan 3 (Yes for S306→S307).

And, when no change is observed in the temperature difference between the indoor temperature of the room and the target (quasi-target) air conditioning temperature or the temperature difference between them gets larger after the lapse of time from the timing A to the timing B, that is, the temperature difference B is larger than the temperature difference A, system controller 8 a determines whether it is an overcooling (for the cooling period) or an overheating (for the heating period) (S308). That is, when the temperature difference gets larger, it may be that a cooling (a heating) beyond the target (quasi-target) air conditioning temperature is provided because the air volume of transfer fan 3 is too large (excessive process), or that the indoor temperature of the room does not approximate the target (quasi-target) air conditioning temperature because the air volume of transfer fan 3 is too small, in addition, the indoor temperature of the room is far from the target (quasi-target) air conditioning temperature due to being affected by an outdoor air. Therefore, system controller 8 a determines which situation is true in S308.

Here, when determined as being the overcooling or the overheating, that is, the excessive process, air volume determining section 24 a determines to reduce the air volume of the transfer fan (Yes for S308→S307).

When determined as being neither the overcooling nor the overheating, that is, not the excessive process, air volume determining section 24 a determines to increase the air volume of the transfer fan (No for S308→S309).

Whether or not it is the overcooling or the overheating, that is, it is the excessive process or not, can be determined from the heating/cooling period setting, the target (quasi-target) air conditioning temperature and the indoor temperature of the room.

Though not indicated in FIG. 9, when there is no difference between the indoor temperature of the room and the target (quasi-target) air conditioning temperature, or the indoor temperature of the room is close to the target (quasi-target) air conditioning temperature (plus or minus 0.3 degrees C., for example), after the lapse of time from the timing A to the timing B, the air volume of the transfer fan may not be changed and it may be maintained.

Fan air volume adjusting process S300 described above is regularly executed.

Through fan air volume adjusting process S300 described above, it makes possible to achieve the target (quasi-target) air conditioning temperature in each of rooms 2 a to 2 i and maintain it by controlling the temperature of the air-conditioned room through air-conditioned room temperature controlling section 23 and controlling the air volume of transfer fan 3.

Air-conditioned room 17 particularly has a significant temperature change because air of various temperatures from each of the rooms is introduced into air-conditioned room 17 by each of the circulation fans. Therefore, for example, it is difficult to provide the above-described control by a system using a pressure difference and a damper, consequently it is important to use transfer fan 3. Although a general fan can be used as the transfer fan to control the temperature in the above-described process, it is desirable, also to provide a fine temperature control, to use a fan equipped with an air volume constant control function as the transfer fan, which is capable of maintaining a certain amount of air volume previously set without being affected by a duct length or pressure.

Even if an interrupt process is executed, for example, changing the target air conditioning temperatures or switching the heating/cooling period settings, the above-described air conditioning process can be executed by starting air-conditioned room temperature control process S100.

By the way, air-conditioned room 17 is a limited volume of space, when it's required to simultaneously cool or heat each of rooms 2 a to 2 i at the maximum air volume (Air Volume 10) for example, it is difficult to applicably maintain the temperature of air-conditioned room 17. This is because a temperature-adjusted air frequently outflows from air-conditioned room 17, while on the contrary, air of a temperature far from that set to air-conditioned room 17 frequently flows into air-conditioned room 17.

Thus, to cope with a case like this, system controller 8 a may execute air-conditioned room load reduction process S400 indicated in FIG. 10. In air-conditioned room load reduction process S400, total air volume calculating section 25 calculates the total air volume, which is the sum of the air volume of each of transfer fans 3 a to 3 i (S401). Then, air volume comparing section 26 compares the total air volume (the sum of the air volume) calculated by total air volume calculating section 25 with the specified threshold value of the air volume previously stored in storing section 30 (S402). Here, the specified threshold value of the air volume is, for example, 80% of the sum of the maximum air volume of each of transfer fans 3 a to 3 i.

Here, when the sum of the air volume exceeds the specified threshold value of the air volume (Yes for S403), air volume comparing section 26 additionally determines whether it is the cooling period or the heating period according to the heating/cooling period setting set by input/output terminal 18 (S404). Air volume comparing section 26 transmits that the sum of the air volume exceeds the specified threshold value of the air volume and that it is the cooling period or the heating period to air-conditioned room temperature controlling section 23. If the sum of the air volume is not greater than the specified threshold value of the air volume (No for S403), the process is terminated.

After air-conditioned room temperature controlling section 23 receives that the sum of the air volume exceeds the specified threshold value of the air volume and that it is the cooling period or the heating period, it changes the temperature of the air-conditioned room to be lower than a currently-set temperature for the cooling period (cooling period for S404→S406). Air-conditioned room temperature controlling section 23 changes the temperature of the air-conditioned room to be higher than the currently-set temperature for the heating period (heating period for S404→S405)

Air-conditioned room temperature controlling section 23 transmits that the temperature of the air-conditioned room is changed to air volume determining section 24 a. According to this, air volume determining section 24 a determines to reduce the air volume of transfer fan 3 (S407).

Thus, a wide temperature range of the target (quasi-target) air conditioning temperature can be provided without increasing the limited volume of air-conditioned room 17 by changing the temperature of air-conditioned room 17 to be lower (cooling period) or to be higher (heating period).

It is advantageous in terms of use efficiency and energy consumption of air-conditioned room 17, not to fix, but to increase a range of reduction (cooling period) or increase (heating period) of the temperature of the air-conditioned room in proportion to how much the sum of the air volume exceeds the specified threshold value of the air volume. Specifically, when the specified threshold value of the air volume is 70 and the sum of the air volume is 80, the temperature is changed by 2 degrees C. Similarly, the temperature is changed by 4 degrees C. for the sum of the air volume of 90, and the temperature is changed by 6 degrees C. for the sum of the air volume of 100.

Next, an air conditioning process executed by system controller 8 a, mainly in the energy-saving control, is explained with reference from FIG. 5 to FIG. 10.

Control switching section 59, which is part of system controller 8 a, confirms whether the operating mode is the normal energy control or the energy-saving control, which is input through input/output terminal 18 by the user and stored in storing section 30 (S1).

Here, when the operating mode is the energy-saving control, control switching section 59 executes a process below through energy-saving controlling section 58 (No for S1). The energy-saving control is the operating mode for controlling the air conditioning controller so that the air conditioning environment of general residence 1 can be close to the user-desired target air conditioning environment within the range of the surplus electric power amount.

Energy-Saving Control

In the energy-saving control, in-house power generation amount obtaining section 54 obtains the power generation amount first through power distribution board 53 (S2). Next, electric power amount obtaining section 55 obtains the consumed electric power amount through power distribution board 53 (S3). In addition, comparing section 56 calculates a difference between the power generation amount and the consumed electric power amount to obtain the surplus electric power.

Here, when the surplus electric power exists, energy-saving controlling section 58 operates air conditioning controlling section 50 by the energy-saving control (Yes for S4). When the surplus electric power does not exist, normal energy controlling section 57 operates air conditioning controlling section 50 by the normal energy control (No for S4).

Only different points between the energy-saving control and the normal energy control are explained hereinafter.

To set a temperature of the air-conditioned room in the energy-saving control (S103 in FIG. 7), air-conditioned room temperature controlling section 23 sets the target temperature of air-conditioned room 17 (air-conditioned room target air conditioning temperature) to air conditioner 7 (S103).

Here, the target air conditioning temperature of the air-conditioned room is determined in the same manner as the normal energy control. However, comparing section 56 always calculates the surplus electric power amount, therefore, when the surplus electric power amount is almost close to zero (0), air-conditioned room temperature controlling section 23 changes the target temperature (air-conditioned room target air conditioning temperature) to the target air conditioning environment (temperature) with the lower energy burden. Thus, the target temperature (air-conditioned room target air conditioning temperature) is determined within an electric power amount equal to the surplus electric power amount.

When the target temperature (air-conditioned room target air conditioning temperature) is set to a temperature equal to that of the normal energy control within the surplus electric power amount and then the temperature of air-conditioned room 17 reaches this temperature (air-conditioned room target air conditioning temperature), occupied-room air conditioning environment controlling section 21 subsequently executes the process below only to the occupied room.

That is, occupied-room air conditioning environment controlling section 21 executes air volume determining process S206 in fan air volume setting process S200 indicated in FIG. 8 only to the occupied room. Occupied-room air conditioning environment controlling section 21 also executes fan air volume adjusting process S300 indicated in FIG. 9 only to the occupied room. When the occupied room and the unoccupied room replace each other because the occupant moves between them, the process is executed only to the occupied room accordingly. Then, no air conditioning control may be executed, or only a minimum required ventilation may be provided to the unoccupied room.

Thus, it is possible to bring the occupied room to the user-desired target air conditioning environment (temperature) within the range of the surplus electric power.

Even after the above process is continued in the occupied room for a specified time, there is still the surplus electric power, then unoccupied-room air conditioning environment controlling section 22 executes air volume determining process S206 in fan air volume setting process S200 indicated in FIG. 8 to the unoccupied room while occupied-room air conditioning environment controlling section 21 continues the above process. Unoccupied-room air conditioning environment controlling section 22 executes fan air volume adjusting process S300 indicated in FIG. 9 to the unoccupied room. In this case, the quasi-target air conditioning environment (temperature) above described is applied to the unoccupied room.

Thus, the quasi-target air conditioning environment (temperature) can be achieved in the unoccupied room.

Regardless of the above, when there remains enough surplus electric power, unoccupied-room air conditioning environment controlling section 22 may change the quasi-target air conditioning environment (temperature), which is already applied to the unoccupied room, to the target air conditioning environment (temperature). This is also possible to bring the unoccupied room to the most comfortable and user-desired target air conditioning environment (temperature) within the range of the surplus electric power.

The above example describes an example where solar power generation panel 51 is used. However, the generation power amount by solar power generation panel 51 is significantly affected by hours of daylight and always varies. Therefore, directly applying a value of the surplus electric power (amount) may cause a frequent control switching. As such, to applicably use the surplus electric power, the above problem can be solved by applying, for example, 90% of an actually-calculated surplus electric power amount as the value of the above-described surplus electric power.

On the other hand, when the power generation amount reduces, an opposite control is executed. That is, the target air conditioning environment (temperature) applied to the unoccupied room is changed to the quasi-target air conditioning environment (temperature).

Next, system controller 8 a stops controlling the unoccupied room and only controls the occupied room. In addition, the target air conditioning temperature (the target air conditioning temperature of the air-conditioned room) is changed to the target air conditioning environment (temperature) with the lower energy burden.

Thus, when the generation power amount reduces, air conditioning environment appropriate to the situation can be provided. Where the surplus electric power is not enough, for example, at night or it is required to change the target air conditioning temperature of the air-conditioned room to a temperature of excessive low energy burden, the energy-saving control may be switched to the normal energy control.

Second Embodiment

A second embodiment is explained hereinafter. Similarities to a first embodiment are not explained for omission.

Firstly, air conditioning system 19 in accordance with the second embodiment of the present disclosure is explained with reference to FIG. 11 and FIG. 2. FIG. 11 is a connection schematic view of air conditioning system 19 in accordance with the embodiment and FIG. 2 shows an example of room layout of general residence 1 in accordance with the embodiment. And FIG. 2 is as explained in the first embodiment. FIG. 11 is identical to FIG. 1 already explained except that room motion sensor 11 is removed and that system controller 8 b is included instead of system controller 8 a.

Next, functions of system controller 8 b are explained with reference to FIG. 12. FIG. 12 is a schematic function block diagram of system controller 8 b.

System controller 8 b includes air-conditioned room temperature controlling section 23, air volume determining section 24 b, fan air volume controlling section 20, total air volume calculating section 25, air volume comparing section 26 and storing section 30. That is, system controller 8 b includes air volume determining section 24 b instead of air volume determining section 24 a in FIG. 3. System controller 8 b further includes in-house power generation amount obtaining section 54, electric power amount obtaining section 55, comparing section 56 and control switching section 59.

Air volume determining section 24 b includes sensor information obtaining section 35, space information storing section 43, target air conditioning environment obtaining section 33 b, quasi-target air conditioning environment storing section 34 b, room air conditioning environment controlling section 41, non-room air conditioning environment controlling section 42, first temperature comparing section 27, second temperature comparing section 28 and temperature difference comparing section 29.

Space information storing section 43 stores information of each of rooms 2 a to 2 i, the room each being classified into one of a room and a non-room. Each of the rooms is associated with each of room temperature sensors 9 a to 9 i, each of transfer fans 3 a to 3 i and each of circulation fans 6 a to 6 i. Here, the room means a space where it is occupied for a long time while living in a house. That is, the room means a living room (room), a dining room (kitchen and eating space), bedrooms, children's rooms, and so forth. The non-room means a space forming part of the house where the room is not included. That is, the non-room includes a toilet, a storage, a bathroom, a restroom, a dressing room, a hallway, an entrance, and so forth. When the kitchen is normally occupied for a short time, the kitchen may be naturally the non-room and vice versa. Controlled spaces intended for air conditioning may be classified into either the room or the non-room.

Target air conditioning environment obtaining section 33 b, when room 2 is determined as being the room according to information from space information storing section 43, obtains the target air conditioning environment set to room 2 through input/output terminal 18.

Quasi-target air conditioning environment storing section 34 b stores the quasi-target air conditioning environment of the non-room corresponding to the target air conditioning environment. Setting examples of the target air conditioning environment (temperature) of the room and the quasi-target air conditioning environment (temperature) of the non-room according to the information stored by quasi-target air conditioning environment storing section 34 b are indicated below.

During summer, that is, the cooling period, quasi-target air conditioning environment storing section 34 b stores the quasi-target air conditioning temperature for the non-room 2 degrees C. higher than the target air conditioning temperature for the room. Similarly, during winter, that is, the heating period, quasi-target air conditioning environment storing section 34 b stores the quasi-target air conditioning temperature for the non-room 2 degrees C. lower than the target air conditioning temperature for the room.

For example, in FIG. 2, given that the target air conditioning temperature of the room is 20 degrees C. during summer, that is, the cooling period, the quasi-target air conditioning temperature of the non-room is 22 degrees C. Similarly, given that the target air conditioning temperature of the room is 20 degrees C. during winter, that is, the heating period, the quasi-target air conditioning temperature of the non-room is 18 degrees C.

Room air conditioning environment controlling section 41 determines the air volume of each of transfer fans 3 according to the target air conditioning environment (temperature) of the room set by input/output terminal 18 through target air conditioning environment obtaining section 33 b, the temperature of air-conditioned room 17 controlled by air-conditioned room temperature controlling section 23 and the indoor temperature of each of the rooms obtained by each of room temperature sensors 9.

Non-room air conditioning environment controlling section 42 determines the air volume of each of transfer fans 3 according to the quasi-target air conditioning environment (temperature) of the non-room determined based on information from target air conditioning environment obtaining section 33 b and space information storing section 43, the temperature of air-conditioned room 17 controlled by air-conditioned room temperature controlling section 23 and the indoor temperature of each of the non-rooms obtained by each of room temperature sensors 9. A determining procedure of the air volume is as described in the first embodiment.

As above, each of the spaces is divided into the room and the non-room, not the occupied room or the unoccupied room indicated in the first embodiment, Thus, it is possible to provide the room with the user-desired and most comfortable target air conditioning environment and provide the non-room with the quasi-target air conditioning environment with the lower energy burden. Therefore, the energy burden can be lowered compared that the target air conditioning environment is set to each of the rooms. And that, a more comfortable target air conditioning environment is provided to the room expected to be occupied longer than the non-room. As such, there is a high possibility to provide the air conditioning environment comfortable to the occupant and a whole-house air conditioning with a simple structure and the lower energy burden.

Obviously, even if the occupant moves from the room to the non-room, it is unlikely to change the air conditioning environment. Therefore, the adverse effect brought by the sudden environmental change, for example, the shock from the temperature change, can be controlled.

When the occupied room in the first embodiment is considered as the room in the second embodiment and the unoccupied room in the first embodiment is considered as the non-room in the second embodiment, the normal energy control and the energy-saving control explained in the first embodiment are applicable to the second embodiment. That is, room air conditioning environment controlling section 41 controls the output of the air conditioning controller of the room so as to be close to be the target air conditioning environment (temperature) in the room within the electric power amount equal to the surplus electric power amount. When the target air conditioning environment (temperature) is achieved in the room by room air conditioning environment controlling section 41 and there is still the surplus electric power, non-room air conditioning environment controlling section 42 provides the energy-saving control to the non-room within the electric power amount equal to the further surplus electric power amount. That is, non-room air conditioning environment controlling section 42 controls the output of the air conditioning controller of the non-room so as to be close to be the target air conditioning environment (temperature) in the non-room.

Non-room air conditioning environment controlling section 42 controls the output of the air conditioning controller of the non-room so as to be close to be the quasi-target air conditioning environment with the lower energy burden than the target air conditioning environment in the non-room according to the surplus electric power amount.

Thus, the same effect as the first embodiment by the energy-saving control is obtainable.

In the first embodiment and the second embodiment described above, the temperature is taken as the air conditioning environment for explanation. However, the whole-house air conditioning using the air-conditioned room can adjust also a humidity environment of each of the rooms by controlling the humidity environment in the air-conditioned room and the air volume of each of the transfer fans. That is, when focusing on the humidity as the air conditioning environment, the humidity of the air-conditioned room can be maintained at the target air conditioning environment (humidity) where the most comfortable humidity is provided. The occupied room or the room can be maintained at the target air conditioning environment (humidity) by increasing the air volume of the transfer fan, and the unoccupied room or the non-room can be maintained at the quasi-target air conditioning environment (humidity) by providing the air volume of the transfer fan less than that of the occupied room or the room.

Of course, a cleanliness environment (air quality) of each of the rooms can be also adjusted by controlling the cleanliness environment and the air volume of each of the transfer fans in the air-conditioned room. That is, when focusing on the cleanliness as the air conditioning environment, the cleanliness of the air-conditioned room can be maintained at the target air conditioning environment (cleanliness) where the highest cleanliness required is set. The occupied room or the room can be maintained at the target air conditioning environment (cleanliness) by increasing the air volume of the transfer fan, and the unoccupied room or the non-room can be maintained at the quasi-target air conditioning environment (cleanliness) by providing the air volume of the transfer fan less than that of the occupied room or the room.

Thus, for not only the temperature but also the humidity and the cleanliness, an energy-saving whole-house air conditioning can be achieved.

The air conditioning system, system controller 8 a and system controller 8 b in accordance with the present disclosure are explained hereinbefore, the above-described embodiments are only examples, not limited thereto.

For example, circulation fans 6 a to 6 i and transfer fans 3 a to 3 i are communicated with each other by ducts connecting the rooms and the air-conditioned room. However, circulation fans 6 a to 6 i are not necessarily connected by the ducts, a space such as a hallway between the rooms can be also considered as the duct. In this case, the indoor air is transferred to the hallway from the rooms by circulation fans 6 a to 6 i. The air of the hallway transferred from the rooms is introduced into air-conditioned room 17 communicated with the hallway. The air may be introduced into air-conditioned room 17 by separately installing a circulation fan on the hallway wall adjacent to air-conditioned room 17 or by depressurization of air-conditioned room 17 without using the circulation fan. This configuration is expected to reduce efficiency in air circulation compared where each of the rooms is connected to the air-conditioned room by the duct, however it can also contribute to the air conditioning system.

And, the air conditioning system in accordance with the present disclosure is applicable to a single-family house or multi-family building such as an apartment. However, when applied to the multi-family building, a single system is installed per one family, each family is not considered as a single room.

INDUSTRIAL APPLICABILITY
